Everyone knows that there is a certain loss in the operation of the Gongming generator. What is the specific situation of these losses? Sanding concluded that the losses can be roughly divided into five categories.

The losses of Gongming generators can be roughly divided into five categories, namely stator copper loss, iron loss, excitation loss, electrical additional loss, and mechanical loss. In the operation of the generator, almost all losses are expressed in the form of heat.

(1) Stator copper loss is the loss generated by the stator current flowing through the stator winding.

(2) Iron loss is the loss generated by the generator flux in the iron core, mainly the hysteresis loss and eddy current loss generated by the main magnetic flux in the stator core, and also includes additional loss.

(3) Excitation loss, that is, the loss generated by the rotor circuit, is mainly the copper loss generated by the excitation current in the excitation circuit.

(4) The electrical additional loss is more complicated, mainly including the loss of the end leakage flux in the vicinity of the iron component, the loss caused by various harmonic fluxes, the tooth harmonics and the higher harmonics generated on the rotor surface. The iron loss and so on.

(5) Mechanical losses mainly include ventilation loss and bearing friction loss.
